Car audio crossovers are a class of electronic filters designed for use in audio applications such as hi-fi. A dynamic loudspeaker driver that is commonly used is incapable of covering the entire audio spectrum all by itself.

Crossovers split the audio signal into separate frequency bands which can be handled by individual loudspeaker drivers optimized for those frequency bands. Let’s take a closer look at Kenwood’s KE-600 Crossover, KPX-F801 Crossover and Kenwood KPX-L101 Crossover.

Kenwood KE-600 Crossover

Kenwood KE-600, one of the most advanced signal processors, is a 6-Way electronic crossover with built-in parametric equalizer and a DC to DC power supply for high voltage outputs and low noise.

It has input selection, phase switching, variable level controls and the following outputs: subwoofer, low-pass, low-cut, high-cut and high-pass. It is a great component for multi-amp installations and is available for around $370.

Features

● DC to DC converter.

● High-frequency output.

● Input selector.

● Different phase switches.

● Subwoofer output from 30Hz to 800Hz (low-pass).

● 6-way multi-amp configuration.

● Variable level controls.

Kenwood KPX-F801 Crossover

Kenwood KPX-F801 Crossover is a 3-way passive crossover network. It is available for around $75.

Features

● Guard circuit that protects against excessive tweeter inputs.

● Special capacitors and inductors for audio purpose.

● Phase inverter switch for midrange and tweeter.

Kenwood KPX-L101 Crossover

Kenwood KPX-L101 Crossover is a low-pass passive crossover network. It is available for $50.

Features

● Special capacitor and inductor for audio purpose.

● 80Hz crossover.

Remember, an audio crossover splits the incoming audio signal into separate bands that do not overlap at all, and which, when added together, gives the signal unchanged in both frequency and phase response.

Panasonic created a winner in the point and shoot “zoom” category with the Lumix DMC-TZ5. Just about one year later, they have given us the Lumix DMC-ZS1 and the DMC-ZS3. (In the European market they are known as the TZ6 and TZ7 respectively. Am I alone in thinking that continuing the “TZ” brand would make more logical sense? And why is there no ZS2?)

This article will compare the Lumix ZS1 and ZS3.

Beginning with the basic specifications that are identical in both cameras:

• 10.1 Megapixels
• 12x Zoom Range (25-300mm)
• Optical Image Stabilization
• 80-6400 ISO Range
• 27 Scene Modes with Intelligent Auto
• Image Quality rated highest among Digital Compacts with similar features (DPReview.com)

The features that are different (ZS1
vs
ZS3):

• LCD – 2.7″ (230k resolution) vs 3.0″ (460k)
• Image Sensor – 1/2.5″ vs 1/2.33″
• Video – 848×480 30fps video w/mono sound vs 720p 60fps video w/stereo sound

These 3 features add just
over $100 to the price tag
for the ZS3. Yet, in spite of the extra $$$, the Lumix ZS3 is outselling its ZS1 cousin by a large margin. Why??

The reason is that most digital compact camera users are now quite comfortable with using their “point and shoot” camera for their basic video needs. And the difference in this feature is significant when you consider many folks are now viewing on big screen HD televisions.

The other big difference is the LCD screen. While 0.3″ does not seem that big of a deal, when added to double the pixel resolution (230,000 vs 460,000), the view quality of the live view and playback is significant.

With respect to image quality and printing images, in a comparison test against other super zoom cameras, the ZS1 and ZS3 were dual winners at DPReview.com.

The final word comes from those who have actually purchased the camera for personal use. After all, the consumer has the last word in satisfaction.

Checking the user reviews at DPReview.com and Amazon.com, both cameras rated highly – at least 4.16 out of 5. In fact, at Amazon, the Lumix ZS1 rated at an impressive 4.67 (out of 5).

As you make your digital camera buying decision, keep the Panasonic Lumix ZS1 and ZS3 in mind. And do not forget about the Panasonic Lumix DMC-TZ5, which has the same features as the more expensive ZS3 with respect to video and image quality (there have been some upgrades to the way video is recorded in the ZS3 that take up less storage space and give the user an option as to the recording mode, but the TZ5 video is comparable to its newer sibling). Picking up the TZ5 would produce a savings of more than $150.

Ferruccio Lamborghini was a very successful business man who owned various businesses although his main line of business was building and selling tractors. Ferruccio’s philosophy was to work hard in the morning and enjoy himself in the afternoon. One day while racing his Ferrari with his close friend Enzo Ferrari he told him that he didn’t quite think that his car was good enough! Enzo took it the wrong way and replied “what would you know about building sports cars, you only know how to build tractors”? Ferruccio felt insulted and decided to build himself his own sports cars. At first everybody laughed at his big ideas. But in 1963 he opened his state of the art factory in Sant’ Agata in Bolognese about 25km from Bologna.

Ferruccio Lamborghini’s love of bulls was so strong that he would often visit Don Eduardo Miura who was the owner of a famous bull ranch in the region of Seville and who bred several species. It was this passion that led him to name several of his cars after various breeds of bull which were reared on this ranch. In 1966 at The Geneva Motor Show an early prototype car called the P400S received so much attention that it went in to production under a different name as the Miura a 4 litre car with 280 bhp which is named after a savage breed of Bull bred by Don Eduardo Miura himself, and several variations followed including the SV Concept, Roadster, SV, and the Jota A replacement for the Miura was to become the Islero 400GT and Islero 400GTS a 2+2 coupe which was built between 1968 and 1969 and was named after the bull that killed the famous matador Manolete in 1947.

The Espada which is the Spanish word for Sword appeared in 1968 at the Geneva motor show and was designed by Marcello Gandini of Bertone the famous car designer who designed several cars for Lamborghini Other cars which had names related to bull fighting were the Jalpa which made its debut at the Geneva Auto Show in 1981 and was named after a breed of bull. In 1990 Diablo was named after a famous bull fight in 1869 when the Duke of Veragua’s raging bull was in an epic battle with El Chicorro.

Some of the more modern supercars of this era include the Muircéilago who was named after the legendary bull in 1879 whose life was spared by Matador El Lagartijo for his amazing performance in the arena and who survived more than 28 strokes from the estoc at this point the matador decided to spare it its life which is very unusual in bull fighting. Gallardo was the name of one of five famous castles of the fighting bull breed, and in 1943 the Reventon was named after the famous bull that took the life of the Mexican torero Félix Guzmán, and finally the 2008 concept car called the Estoque which is named after the estoc or sword in English language which is used to kill the bull in contest.

Although there was one very special Lamborghini supercar which wasn’t connected to the name of any bull or bullfighting but could quite possibly be referred to as Madonna herself. This was of course the Countach, this came about when famous car designer Giuseppe Bertone first set eyes on the car. He was almost speechless except for one word which he managed to utter! This word was of course Countach which is often said as an act of astonishment and quite often used by Piedmontese men when they first set eyes on a beautiful woman.

On the exterior is also what you would expect with high quality car like this with its metallic paint work and privacy glass windows and chrome finish around the windows and bumpers, grill, twin exhausts and wheels too. Not also forgetting that the Touareg has both front and rear sensor parking which makes parking problems a thing of the past.

The power output transistors would be silver and on the inside wall of the heatsink. The thing you are referring to as being black is most likely a thermal cut-off switch. If it gets too hot (indicating a problem with the output transistors) it will tell the amp to shut down or go into protection mode so no further damage will be done until the unit gets checked out and repaired.

I remember years ago a customer of mine called because she was stranded at McDonalds. Her car wouldn’t start, it wouldn’t even crank over. Luckily I was only about five minutes away and was able to drop by to check her car for her. The battery terminals were after-market, the type that has two 7/16″ bolts that clamp over the bare cable end. These are a quick easy repair for the battery cable but sometimes they do loosen over time. That was exactly what had happened in this case. I was able to just tighten the terminals where they clamped to the bare cable ends and she was on her way.

A car that doesn’t turn over at all, usually has a battery related problem. Many cars are towed to auto repair shops every year due to loose or corroded battery terminals. If the car engine doesn’t crank over at all, the first thing to check is the battery and terminal connections. Here’s a quick auto repair tip, turn the lights on and try the horn. If the battery is any good at all this will be a quick preliminary check. If there’s no horn and no lights, try wiggling the battery connections. I leave the lights on while trying this so I can tell if I’m making a better connection when moving the battery terminals.

Still no luck? A load test with a battery tester is the next step after checking the connections at the battery. Many times a battery will show signs of failure by turning the engine over slowly when it’s beginning to fail, this is an early warning to have the battery tested. Unfortunately other times batteries will just fail with no prior warning. Temperature changes can sometimes reveal a problem with a battery that otherwise may go unnoticed. An increase or decrease of temperature will typically send cars in droves to the repair shop or parts stores with sluggishly starting cars. Batteries will need to have a good charge before they can be properly tested. Modern battery testers will indicate if the battery has a sufficient charge to be checked.

Alternators that are not charging properly can cause a car to have similar symptoms. It’s always a good idea to check the alternator to make sure the output is within the manufacturer’s specifications. The parts store or auto repair shops have the test equipment to check the alternator output for you. They will check the amperage, volts, diode pattern and check to see if the alternator has a draw or short that may be excessively draining the battery.

Starters can draw excessive amps or have an open circuit completely. After checking to make sure a good battery is installed, check the big cable connection at the starter which is the 12v one that comes directly from the battery. Then check at the starter solenoid (the small wire) to see if it is getting power when the ignition is turned to the start position. If power is going to the starter solenoid but the starter is not engaging, more than likely the starter has an open circuit or is binding. Sometimes the starter can be tapped with a hammer while the ignition is in the start position to get the car to start. This is basically to get the car into the shop for starter replacement. I’ve used this trick many times over the years to keep from having to push the car into my service bay. The starter can also be tested to see if it is creating too much of a draw on the battery. This can happen when the starter begins to to drag or bind and puts too much of a toll on the battery. The amp draw is measured with a battery and electrical system tester to see if it is excessive.

My tips and tricks have been picked up over the years with real hands on experience. Many auto techs don’t like to share their techniques, but I’ve been selling tools since 2005 and it’s time to share what I’ve learned during my time as a Master Automotive Technician. I hope my article helps many people to figure out what’s going on with their car and just maybe help prevent them from being stranded.
